Maybe I am missing something as I am surprised this has not been more documented, but how do you "subscribe" to a calendar feed generated by Solspace Calendar?
My expected result would be that after adding a calendar by URL in Google Calendar, any changes I make to the calendar's events in EE would be reflected in Google Calendar.
The URLs I have tried (as per this question) are:
http://mydomain.com/events/icalendar-template
webcal://mydomain.com/events/icalendar-template
where /events/icalendar-template looks like this {exp:calendar:icalendar}{/exp:calendar:icalendar}
and spits out the .ics file on direct visit via http://
On adding the calendar in Google Calendar, the events are correctly pulled through initially, but then don't update when I make changes in the EE.
I have also tried using a query string for the URL (as per this thread) just in case the problem was Google Calendar's but that hasn't fixed it.
EE version: 2.9.0, SC version: 1.8.9
